 line F passes through points (7,1) and (2,9). Line g is perpendicular to f. What is the slope of line g?
Answer:
5/8
Step-by-step explanation:
To find a perpendicular line, it is important to first find the slope. Two points are given, so the slope can be found by using the slope formula. However, it is also possible to find the slope by counting the differences. Slope is rise over run. That means the change in y over x. Therefore, since the y-value increases by 8 and the x-value decreases by 5, the slope is -8/5.
Perpendicular lines have opposite and reciprocal slopes. This means that if the slope for a line is a/b, then the perpendicular slope with be -b/a. Thus, the slope of line g is 5/8.

To graph y=x^2-4, you would shift the graph of y=x^2 ____ a distance of ____ units?
Answer:
"To graph y = x² - 4, you would shift the graph of y = x² _down_ a distance of __4__ units.
Step-by-step explanation:
Start with the parent function
y = x²
When you substitute y - k for y, you are shifting the graph vertically k units.
The translated function is
y = x² - 4
Add 4 to both sides.
y + 4 = x²
y was substituted by y + 4.
We must write the substitution as y - k, so rewrite y + 4 as
y - (-4). Now compare y - (-4) with y - k.
k = -4
The vertical shift is -4, so the graph was translated 4 units down.
"To graph y = x² - 4, you would shift the graph of y = x² _down_ a distance of __4__ units.
To draw graph y = x² - 4, we shift the graph y = x² down a distance of 4 units.
What is Quadratic equation?
An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Draw the graph y = x² - 4 with the help of graph y = x².
Now,
Since, The translated graph is,
y = x² - 4
Add 4 both side, we get;
y + 4 = x²
Clearly, y is substituted by y + 4.
Since, when we substitute y - k for y , then we shift k units down.
So, By comparing we get;
y + 4 = y - (-4)
The graph y = x² - 4 is shift down to 4 units.
Thus, To draw graph y = x² - 4, we shift the graph y = x² down a distance of 4 units.

Which of the following formulas would use an absolute row reference when filled
=B4*B6
=B4/$B6
=$B4*B6
=B$4*B6
When filled, the formula that utilizes an absolute row reference is =$B4*B6. Option (A) B4*B6 is the correct answer.
How to use a formula for an absolute row?In the formula, the dollar sign before B locks the reference to column B, while the absence of a dollar sign before row number 4 allows the row reference to be adjusted when the formula is copied or filled down to other cells.
This means that when the formula is copied or filled down to the cells below, the row reference will stay the same as row 4, while the column reference will change based on the column of the new cell.
The formula =B4*B6, on the other hand, would include relative references to both the row and the column, thus when copied or filled down, both the row and column references would alter based on the new cell.
The formulas =B4/$B6 and =B$4*B6 would have an absolute column reference and a relative row reference, meaning that when copied or filled down, the column or row references, respectively, would stay the same or adjust based on the new cell.
Therefore, the formula =$B4*B6 is the one that uses an absolute row reference when filled.

Are 2/3 and 8/12 equivalent ratios? If so, what can you multiply one by to get to the other?
Answer:
Yes
Step-by-step explanation:
Yes, since the relationship between the denominators can be expressed as x(4) = y, then you must apply this to the numerators as well. If you multiply 2 by 4 the result is 8, which aligns with the 2nd ratio - in fraction form.
I hope this helped a bunch! Tell me if you need any further assistance...
( :
Answer:
Yes
Step-by-step explanation:
2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.
